(Summary description)The vacuum freeze dryer is different from the bell-type small freeze dryer used in the traditional laboratory. It has the function of in-situ freeze-drying, box-type closed design, rigorous structure, small size and strong flexibility. It is suitable for life sciences\medicine\ Food science\aquatic science\biochemistry\environmental science and archaeology and other scientific researches can meet customer needs for freeze-drying process exploration and technical application. Compared with the traditional pilot freeze-drying machine with the same freeze-drying area, the vacuum freeze-drying machine is small in size and affordable; compared with the traditional laboratory small freeze-drying machine, it is easy to operate, freeze-drying in situ, and avoid the material drying process Pollution and labor

Information

The vacuum freeze dryer is different from the bell-type small freeze dryer used in the traditional laboratory. It has the function of in-situ freeze-drying, box-type closed design, rigorous structure, small size and strong flexibility. It is suitable for life sciences\medicine\ Food science\aquatic science\biochemistry\environmental science and archaeology and other scientific researches can meet customer needs for freeze-drying process exploration and technical application.

Compared with the traditional pilot freeze-drying machine with the same freeze-drying area, the vacuum freeze-drying machine is small in size and affordable; compared with the traditional laboratory small freeze-drying machine, it is easy to operate, freeze-drying in situ, and avoid the material drying process Pollution and cumbersome manual operations.

Design features of freeze dryer:

1. Good drainage design: 20° inclined angle design, the water can be discharged smoothly when the ice is melting, avoiding the spray of residual water during the next operation, and it does not need to be manually wiped and is not easy to be polluted.

2. Intelligent PLS control: PLS automatic operation controller, large-screen color screen, touch man-machine interface, digital display of various data such as temperature, vacuum, voltage, and all operations and alarms in the process are recorded.

3. Fast freezing design: Fully automatic control of good freezing efficiency, which can be quickly cooled to -80/-50℃ or below within 10 minutes after startup, ensuring that the sample can be frozen quickly when a large amount of water vapor is released instantly, without losing temperature And produce melting ice.

4. System protection function: It has the function of self-protection of temperature and vacuum degree. When abnormal, it will alarm and generate buzzer. The vacuum pump will be automatically turned off if the vacuum degree is abnormal for more than 10 minutes to avoid failure due to vacuum pumping for too long.

5. Automatic data recording: It conforms to the cGMP design, can trace the conditions in the operation process, and ensure whether there is any abnormality during the operation process.

Features:

1. In-situ pre-freeze drying function;

2. Adjustable temperature and controllable production process, set up different processes according to different materials;

3. Multiple sections can be set, program parameters can be modified during operation, and vacuum drying curve and data can be recorded online;

4. Touch screen, can set power-on password, display drying curve;

5. The square tray is not easy to deform, easy to operate and easy to clean;

6. Equipped with inflation valve, optional inert gas inflation device;

7. The drying room adopts high-transmittance, colorless and transparent plexiglass door, which can clearly observe the changing process of materials during operation;

8. Models LFD-1, LFD-4, LFD-1A, LFD-4A can be equipped with oil-free vacuum pumps, which can solve the problems of oil change, oil mist and anti-corrosion;

9. Models LFD-6, LFD-4, LFD-6A, LFD-4A adopt PLC control system, which can be started by one key.

10. The vacuum freeze dryer can use automatic operation mode. When the temperature of the cold trap meets the freeze-drying conditions, the vacuum pump will automatically start.

11. The timing function can display the vacuum pump operating time, cumulative operating time, freeze-drying time, etc., which is convenient for users to calculate the time to replace the pump oil and calculate the sublimation time.

12. The cold trap is relatively independent of the freeze-drying bin and multi-manifold, which can easily observe the icing condition in the cold trap and facilitate timely deicing.

13. A cold trap sensor can be purchased. When the ice capacity of the cold trap is close to the maximum ice capacity, the sensor will automatically alarm.

Freeze-dried items are easy to store for a long time, and can be restored to the state before freeze-drying after adding water and maintain the original biochemical properties. For heat-sensitive substances such as antibiotics, vaccines, blood products, enzyme hormones and other biological products, the freeze-drying technology of the vacuum freeze dryer can even show its superiority.
